{"@context":"https://schema.org","@type":"DefinedTerm","name":"Marine Fuel Lifecycle Assessment (Well-to-Wake)","description":"Unlike tank-to-wake analysis, which covers only combustion emissions produced onboard, Well-to-Wake lifecycle assessment traces the full greenhouse gas chain of a marine fuel—from extraction and refining through distribution to final combustion in the engine. This matters most when comparing fuels: LNG may produce fewer exhaust emissions than heavy fuel oil yet carry significant upstream methane losses, making the Well-to-Wake balance less favourable than a tank-to-wake figure suggests.
